Title: Laminated glass mfr. using polyvinyl butyral film
Inventor: MORTELMANS JOHAN FRANS
IPC: B29C48/13
Filed: 1995-05-27
Abstract: A conventional process for mfg. laminated glass comprising a polyvinylbutyral film (2) sandwiched between glass layers uses the roughness of the film at temps. >120 deg C to exclude air trapped at the glass/film interfaces. Additional air channels to enhance air exclusion are created by forming long thin areas (3) across the film (2) width at a much lower temp. than that at which the roughness is produced. The visco-elastic behaviour of the film (2) during or after pressing together of the glass/film layers ensures that the air channels (3) disappear before the assembled laminate is compressed under heat in an autoclave.  In a claimed process for mfg. the polyvinylbutyral film the film surface is roughened during or after extrusion and the film passed at 50-120 deg C over a rotating cooled roll (4) with grooves (5). Cooling differences in the film (2) opposite the roll (4) surface and grooves (5) produce thin areas opposite the grooves (5).

Title: Appts. for determn of position of moving element e.g. for electric remotely controlled vehicle sun-roof or windows
Inventor: TORII KATSUHIKO
IPC: G01D5/245
Filed: 1996-01-26
Abstract: The appts. is used to detect a predetermined movement position of the movable element which moves forwards and backwards. A switch region (50) is completely attached in a housing (34,36) and has at least one pair of sprung contact terminals (60) which are switched on and off. A planetary gear mechanism has a ring gear wheel (46) and a planet wheel (54) fixed in the housing (34,36). The planetary gear is coupled to the movable element (20) via a movement force transmitted from the movable element (20). The ring wheel (46) is arranged such that it switches the switch (50) on or off when the movable element is in a predetermined position. A coupling mechanism (52,40) in the housing normally transmits the movement force of the movable element (20) from the planet wheel (54) to the ring wheel (46), where the rotation of the planet wheel is prevented, to rotate the ring wheel. The coupling mechanism interrupts transmission of a rotation force in the forward direction from the movable element (20) to the ring wheel, where rotation of the planet wheel is allowed, in a condition where the switch (50) is on or off. A control circuit (80) is connected to the switch (50) to detect the predetermined position of the element (20) when the switch (50) is on or off.

Title: Self-locking ball joint for piston-cylinder aggregate Ball joint
Inventor: MAURY HORST DIPL ING
IPC: F16C11/06
Filed: 1996-09-18
Abstract: A ball joint especially for a piston-cylinder aggregate, incorporates a ball dish with a spherical indentation. When assembled, the ball (15) fits in the recess (9). A movable locking part (11) completes the recess and holds the ball in position.
